Answer 1

Number 1 = True
"The Muslim overlords generally displayed tolerance toward the religions of dhimmi peoples. Though they had to pay the jizya and both commercial and property taxes, their communities and legal systems were left intact and they were allowed to worship as they pleased. This approach made it a good deal easier for these peoples to accept Arab rule."

Number 2 = True (This word entered English in 1562, from the Turkish vezir ("counsellor"), from the Persian vazier, literally "one who bears (the burden of office)".
The Muslim office of vizier, which spread from the Persians to the Arabs, Turks, Mongols and neighbouring peoples (regardless of the style of the ruler), arose under the first Abbasid caliphs and took shape during its tenure by the Barmecides as the chief minister or representative of the caliph. The vizier stood between sovereign and subjects, representing the former in all matters touching the latter. This withdrawal of the head of the state from direct contact with his people was unknown to the Omayyads, and was certainly an imitation of Persian usage. It has even been plausibly conjectured that the name is simply the Arabic adaptation of a pre-Islamic Persian title, vichir (Middle Persian for Vizier), who was a minister to the Shah. According to Klein, the Arabic word wazir is derived from Avestan vicira "arbitrator, judge" and replaced the Arabic kātib, "writer" in the sense of "secretary of state".
However, the term has been used in two very different ways: either for a unique position, the prime minister at the head of the monarch's government (the term Grand Vizier always refers to such a post), or as a shared 'cabinet rank', rather like a British secretary of state. If one such vizier is the prime minister, he may hold the title of Grand Vizier or another title.)

Number 3 - False - the merchants of Mecca hated Muhammed; he was bad for business.
"The merchants of Mecca were angry with Mohammed for his doctrine of Allah and submission to him. His ideas upset their businesses and they opposed him. But he gathered his strength and eventually overtook them by the sword. In time, he used the sword effectively in defeating his enemies – pagans, Jews and Christians – giving them the opportunity to convert to Islam. "
